I cut back my Ivory Halo Dogwood shrub dogwood right back in late winter which was the beginning of March here in Calgary, Alberta, Canada. It was growing in so many poor directions that pruning only a third out wouldn't have created a nice, healthy shape. As much as I didn't want to lose it for the season, I felt it was the correct thing to do.

Yesterday I noticed a slimy, dark green, barnacle-like "fungus"? growing all over the crown and most of the cut branches. It may have been over watered with the sprinkler my husband had running as I had also watered the beds prior to that. The others I cut back or pruned in seperate locations are all fine.

If not, are there any suggestions of what I should be looking up to see if I can fix whatever is going on?

Much appreciated!

You need to remove the mulch and aerate the soil about two inches deep. Don't let any water hit the wood anymore if you can keep off. Don't water at all, and let the soil dry out about 6 inches deep.

Thank you Oneeyeluke!

I have taken your advice and will let you know the results. Fingers crossed!
